Description

Technical Field

[0001] The invention relates to a feeding device, in particular to an automatic pipe feeding machine. Background Art

[0002] Before processing, pipes are usually placed in a storage rack. The storage rack has space for accommodating pipes, and an outlet is provided on the side wall or bottom of the storage rack. When the pipes need to be released, the pipes are released one by one from the outlet. Since the space in the storage rack is large, multiple pipes can be placed side by side at the same time. Therefore, when the pipes are stacked in the storage rack, they are prone to cross each other. For example, if two pipes are not placed parallel to each other but cross each other, it will be difficult for the pipes to fall out of the outlet. In addition, the existing storage rack is prone to the problem of pipe jamming when discharging materials, that is, two pipes are stuck at the outlet at the same time, and the outlet that can only allow one pipe to pass cannot allow the pipe to pass.

[0003] Traditional pipe feeders directly add a blocking mechanism at the outlet of the storage rack, and use the blocking mechanism to release the pipes one by one. However, this pipe loading method is not stable, and the problem of releasing multiple pipes at a time often occurs, resulting in feeding confusion and affecting subsequent processing operations. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic pipe feeding machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The solution of the present invention to solve its technical problem is:

[0006] The loading platform is configured to load the material into the feed container and the feed container to form a feed container, wherein the loading platform is configured to load the material into the feed container, and the loading platform is configured to load the material into the feed container. Mechanism; a guide frame, wherein an inclined guide channel and a vertical guide channel are provided in the guide frame, the inclined guide channel is inclined downward from front to rear, the front end of the inclined guide channel is communicated with the discharge port, the rear end of the inclined guide channel is communicated with the top end of the vertical guide channel, a tube pressing translation device is provided on the guide frame, a tube pressing plate is provided on the tube pressing translation device, the tube pressing translation device can drive the tube pressing plate to move along the front and rear direction in the vertical guide channel, a trustee lifting device is provided on the guide frame, a trustee lifting device is provided on the trustee lifting device, a trustee plate is provided on the trustee lifting device, a limiting groove is provided on the top surface of the trustee plate, and the trustee lifting device can drive the trustee plate to enter and exit the vertical guide channel from the bottom end of the vertical guide channel.

[0007] This technical solution has at least the following beneficial effects: a storage space for storing pipes is provided in the storage rack, and the external pipes placed on the loading rack can be placed into the storage space from the opening through the loading mechanism, and the top surface of the limit frame and the top surface of the guide bottom plate form a conical storage bottom surface, so that when the pipe is placed in the storage space, the pipe will roll along the conical storage bottom surface, and the pipe will be parallel to the extension line in the left and right directions, reducing the phenomenon of crossing between the pipes, and a limiting gap is formed between the bottom surface of the limit frame and the top surface of the guide bottom plate for the pipe to pass through, and the limiting gap is for a single pipe to pass through, so that multiple pipes will not be squeezed near the discharge port at the same time, avoiding the pipes being unable to pass through the discharge port. In order to solve the problem of the material port falling off, after the pipes are discharged from the material port one by one, they first enter the inclined guide channel, and under the action of gravity, enter the vertical guide channel, so that multiple pipes are arranged one by one in the vertical direction. At this time, the pipe at the bottom enters the limiting groove of the hosting plate, and then the pipe pressing translation device drives the pipe pressing plate to press the pipe, and the second or more pipes from the bottom are pressed against the side wall of the vertical guide channel. Finally, the hosting lifting device drives the hosting plate to descend, so that only a single pipe can be released each time. Therefore, the present invention can not only realize the orderly arrangement of pipes during storage and increase the storage space, but also avoid the problems of pipe jamming during discharging and discharging multiple pipes at a time, and the output is more stable.

[0008] As a further improvement of the above technical solution, a first pneumatic push rod is provided on the left side of the vertical guide channel, a left clamping plate is provided on the first pneumatic push rod, and the first pneumatic push rod drives the left clamping plate to move in the left-right direction, and a second pneumatic push rod is provided on the right side of the vertical guide channel, and a right clamping plate is provided on the second pneumatic push rod, and the left clamping plate and the right clamping plate are arranged opposite to each other, and the second pneumatic push rod drives the right clamping plate to move in the left-right direction. After the pipe enters the vertical guide channel, there will be a problem that the head end or tail end of each pipe is not aligned. At this time, the first pneumatic push rod is used to drive the left clamping plate, and the second pneumatic push rod is used to drive the right clamping plate to move in the direction close to the pipe. In this way, the left clamping plate and the right clamping plate form a clamping space, which can clamp and align the pipe in the vertical guide channel, thereby ensuring that the pipe is in the same position each time it is discharged, reducing subsequent processing errors.

[0009] As a further improvement of the above technical solution, the feeding mechanism includes a lifting screw rod arranged on the feeding rack, a load-bearing beam arranged on the lifting screw rod, and a guide rod arranged on the load-bearing beam. The lifting screw rod can drive the load-bearing beam to move in a vertical direction. The load-bearing beam extends in a left-right direction. A plurality of guide rods are evenly arranged on the load-bearing beam along the length direction of the load-bearing beam. The guide rods extend downward from front to back. A material stopping groove is arranged on the front side of the storage rack. The material stopping groove extends in a vertical direction. The bottom end of at least one guide rod extends into the material stopping groove. The top surfaces of multiple guide rods together form a loading guide surface, and the external pipes to be loaded are stacked on the loading guide surface. Since the loading guide surface is tilted downward from front to back, the pipes tend to move backward and downward and are blocked by the storage rack. When the lifting screw drives the load-bearing beam upward, the pipes located above are higher than the front side of the storage rack and enter the guide bottom plate to realize loading, and this continues until all the pipes on the loading guide surface are lifted up and fall onto the loading guide surface.

[0010] As a further improvement of the above technical solution, a transition assembly is provided on the material storage rack, and the transition assembly includes a transition lifting cylinder provided on the material storage rack and a transition plate provided on the transition lifting cylinder. The transition lifting cylinder can drive the transition plate to move in the vertical direction, and the transition assembly is evenly provided with multiple transition plates in the left and right directions. The transition plate can fill the space when the pipes on the material loading rack fall to the material storage rack, so that the pipes can enter the material storage space more smoothly. The transition plate can move in the vertical direction driven by the transition lifting cylinder, and the adjustment is more convenient.

[0011] As a further improvement of the above technical solution, a pneumatic push rod is provided on the front side of the storage rack, and a blocking rod is provided on the pneumatic push rod, and the lifting device can drive the blocking rod to enter or leave the discharge port. When it is not necessary to discharge the pipe, the pneumatic push rod drives the blocking rod to descend, so that the blocking rod enters the discharge port to prevent the pipe from falling. When it is necessary to discharge the pipe, the lifting device drives the blocking rod to rise, so that the blocking rod leaves the discharge port, so that the pipe can fall.

[0012] As a further improvement of the above technical solution, a vibration motor is provided on the bottom surface of the guide bottom plate. When the vibration motor is working, the guide bottom plate can be vibrated, thereby vibrating the pipes off. If the pipes are placed crosswise or stacked on each other and cannot enter the limit gap, the vibration of the guide bottom plate can realize the arrangement of the pipes so that the pipes can smoothly enter the limit gap.

[0013] As a further improvement of the above technical solution, a front buffer is provided at the front end of the guide bottom plate, and the front buffer comprises a front connecting plate and a first buffer spring. The front end of the guide bottom plate is rotatably connected to the front connecting plate, the top end of the first buffer spring is fixed to the bottom surface of the front connecting plate, and the bottom end of the first buffer spring is fixed to the storage rack. The buffering effect of the first buffer spring can reduce the vibration of the guide bottom plate transmitted from its front end to the storage rack, thereby reducing noise and improving the stability of the structure.

[0014] As a further improvement of the above technical solution, a rear buffer is provided at the rear end of the guide bottom plate, and the rear buffer includes a rear connecting plate and a second buffer spring, the top end of the second buffer spring is fixed to the bottom surface of the guide bottom plate, the bottom end of the second buffer spring is fixed to the rear connecting plate, and the rear connecting plate is fixedly connected to the storage rack. Similarly, by utilizing the buffering effect of the second buffer spring, the vibration of the guide bottom plate can be reduced from being transmitted from its rear end to the storage rack, further reducing noise and improving the stability of the structure.

[0015] As a further improvement of the above technical solution, the tube pressing translation device is a translation cylinder, that is, the translation cylinder is used to drive the tube pressing plate to move in the front-rear direction.

[0016] As a further improvement of the above technical solution, the hosting lifting device is a lifting cylinder, that is, the lifting cylinder is used to drive the hosting plate to move in the up and down directions. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figure 1 , Figure 2 and Figure 3A pipe automatic feeding machine includes a frame, on which a storage rack 100 is provided, wherein the storage rack 100 has a storage space opening upward, and a discharge port 110 communicating with the storage space is provided at the bottom of one side of the storage rack 100, and a guide bottom plate 210 and a limit frame 310 are provided in the storage space with the discharge port 110 facing the rear relative to the storage space, wherein the top surface of the guide bottom plate 210 is downward from front to back. The top surface of the guide bottom plate 210 is tilted, the rear end of the top surface of the guide bottom plate 210 extends to the discharge port 110, the top surface of the limit frame 310 is tilted downward from back to front, the bottom surface of the limit frame 310 is parallel to the top surface of the guide bottom plate 210, the limit frame 310 is fixed to the rear side of the storage rack 100, and a limit gap is formed between the bottom surface of the limit frame 310 and the top surface of the guide bottom plate 210; the guide frame 500 has a The inclined guide channel 510 and the vertical guide channel 520, the inclined guide channel 510 is inclined downward from front to back, the front end of the inclined guide channel 510 is communicated with the discharge port 110, and the rear end of the inclined guide channel 510 is communicated with the top of the vertical guide channel 520. The guide frame 500 is provided with a tube pressing translation device 530, and the tube pressing translation device 530 is provided with a tube pressing plate 531, and the tube pressing translation device 530 can drive the tube pressing plate 531 to move in the front and rear directions in the vertical guide channel 520. The guide frame 500 is provided with a hosting lifting device 540, and the hosting lifting device 540 is provided with a hosting plate 541, and the top surface of the hosting plate 541 is provided with a limiting groove, and the hosting lifting device 540 can drive the hosting plate 541 to enter and exit the vertical guide channel 520 from the bottom end of the vertical guide channel 520.

[0025] As can be seen from the above, the storage rack 100 has a storage space for storing pipes, and pipes can be added to the storage space from the opening. The top surface of the limit frame 310 and the top surface of the guide bottom plate 210 form a conical storage bottom surface, so that when the pipe is put into the storage space, the pipe rolls along the conical storage bottom surface, and the pipe will be parallel to the extension line of the left and right directions, reducing the phenomenon of the pipes crossing each other. In addition, a limiting gap for the pipe to pass through is formed between the bottom surface of the limit frame 310 and the top surface of the guide bottom plate 210. The limiting gap is for a single pipe to pass through, so that multiple pipes will not be squeezed near the discharge port 110 at the same time, avoiding the problem that the pipe cannot fall from the discharge port 110, and the pipes are discharged from the discharge port one by one. After being discharged, 110 first enters the inclined guide channel 510, and under the action of gravity, enters the vertical guide channel 520, so that multiple pipes are arranged one by one in the vertical direction. At this time, the pipe at the bottom enters the limiting groove of the holding plate 541, and then the pipe pressing and translation device 530 drives the pipe pressing plate 531 to press the pipe, and the second or more pipes from the bottom are pressed against the side wall of the vertical guide channel 520. Finally, the holding lifting device 540 drives the holding plate 541 to descend, so that only a single pipe can be accurately released each time. Therefore, the present invention can not only realize the orderly arrangement of pipes during storage and increase the storage space, but also avoid the problems of pipe jamming and multiple pipes being discharged at a time during discharging, and the output is more stable.

[0026] In actual use, multiple guide base plates 210 and limit frames 310 can be evenly arranged along the left and right directions. The number of settings mainly depends on the length of the pipe. The longer the length of the pipe, the more guide base plates 210 and limit frames 310 can be set.

[0027] After the pipe enters the vertical guide channel 520, the head end or tail end of each pipe may not be aligned. Therefore, in this embodiment, a first pneumatic push rod 551 is provided on the left side of the vertical guide channel 520, and a left clamping plate is provided on the first pneumatic push rod 551. The first pneumatic push rod 551 drives the left clamping plate to move in the left-right direction. A second pneumatic push rod is provided on the right side of the vertical guide channel 520, and a right clamping plate is provided on the second pneumatic push rod. The left clamping plate and the right clamping plate are arranged opposite to each other, and the second pneumatic push rod drives the right clamping plate to move in the left-right direction. The first pneumatic push rod 551 drives the left clamping plate, and the second pneumatic push rod drives the right clamping plate to move in the direction close to the pipe. In this way, the left clamping plate and the right clamping plate form a clamping space, and the pipe located in the vertical guide channel 520 can be clamped and aligned, thereby ensuring that the pipe is in the same position each time the material is discharged, reducing subsequent processing errors.

[0028] The feeding mechanism is used to feed the pipes on the feeding rack 600 into the storage rack 100. The feeding mechanism includes a lifting screw rod 611 arranged on the feeding rack 600, a load-bearing beam 612 arranged on the lifting screw rod 611, and a guide rod 613 arranged on the load-bearing beam 612. The lifting screw rod 611 can drive the load-bearing beam 612 to move in the vertical direction. The load-bearing beam 612 extends in the left and right directions. A plurality of guide rods 613 are evenly arranged on the load-bearing beam 612 along the length direction of the load-bearing beam 612. The guide rods 613 extend downwardly from front to back. A material stopping groove is arranged on the front side of the storage rack 100. The material stopping groove extends in the vertical direction. The bottom end of at least one of the guide rods 613 extends into the material stopping groove. The top surfaces of multiple guide rods 613 together form a loading guide surface, and the external pipes to be loaded are stacked on the loading guide surface. Since the loading guide surface is tilted downward from front to back, the pipes tend to move backward and downward and are blocked by the storage rack 100. When the lifting screw rod 611 drives the load-bearing beam 612 to rise, the pipes located above are higher than the front side of the storage rack 100 and enter the guide bottom plate 210 to realize loading, and this continues until all the pipes on the loading guide surface are lifted up and fall onto the loading guide surface.

[0029] In order to make the pipe material loading rack 600 fall to the storage rack 100 more smoothly, a transition assembly is provided on the storage rack 100, and the transition assembly includes a transition lifting cylinder 621 provided on the storage rack 100, and a transition plate 622 provided on the transition lifting cylinder 621. The transition lifting cylinder 621 can drive the transition plate 622 to move in the vertical direction, and the transition assembly is evenly provided with multiple transition plates along the left and right directions. The transition plate 622 can fill the space when the pipe material on the loading rack 600 falls to the storage rack 100, so that the pipe material can enter the storage space more smoothly. The transition plate 622 can move in the vertical direction driven by the transition lifting cylinder 621, and the adjustment is more convenient.

[0030] In order to conveniently control the discharge of materials from the discharge port 110, in this embodiment, a pneumatic push rod 410 is provided at the front side of the storage rack 100, and a blocking rod 420 is provided on the pneumatic push rod 410. The lifting device can drive the blocking rod 420 to enter or leave the discharge port 110. When it is not necessary to discharge the pipe, the pneumatic push rod 410 drives the blocking rod 420 to descend, so that the blocking rod 420 enters the discharge port 110 to prevent the pipe from falling. When it is necessary to discharge the pipe, the lifting device drives the blocking rod 420 to rise, so that the blocking rod 420 leaves the discharge port 110, so that the pipe can fall.

[0031] In order to ensure that the pipes on the guide bottom plate 210 can roll down smoothly, a vibration motor 220 is provided on the bottom surface of the guide bottom plate 210. When the vibration motor 220 is working, the guide bottom plate 210 can be vibrated, so that the pipes can be shaken off. If the pipes are placed crosswise or stacked on each other and cannot enter the limiting gap, the vibration of the guide bottom plate 210 can realize the arrangement of the pipes so that the pipes can enter the limiting gap smoothly.

[0032] When the vibration motor 220 vibrates the guide bottom plate 210, the vibration will also be transmitted to the entire storage rack 100, which will affect other connection structures, such as Figure 4 As shown, a front buffer is provided at the front end of the guide bottom plate 210, and the front buffer includes a front connecting plate 230 and a first buffer spring 240. The front end of the guide bottom plate 210 is rotatably connected to the front connecting plate 230, the top end of the first buffer spring 240 is fixed to the bottom surface of the front connecting plate 230, and the bottom end of the first buffer spring 240 is fixed to the storage rack 100. By utilizing the buffering effect of the first buffer spring 240, the vibration of the guide bottom plate 210 can be reduced from the front end thereof to the storage rack 100, which can reduce noise and improve the stability of the structure.

[0033] In order to further reduce the impact of the vibration of the vibration motor 220, a rear buffer is provided at the rear end of the guide bottom plate 210, and the rear buffer includes a rear connecting plate 250 and a second buffer spring 260. The top end of the second buffer spring 260 is fixed to the bottom surface of the guide bottom plate 210, and the bottom end of the second buffer spring 260 is fixed to the rear connecting plate 250. The rear connecting plate 250 is fixedly connected to the storage rack 100. Similarly, by utilizing the buffering effect of the second buffer spring 260, the vibration of the guide bottom plate 210 can be reduced from being transmitted from its rear end to the storage rack 100, thereby further reducing noise and improving the stability of the structure.

[0034] In some embodiments, the tube pressing translation device 530 is a translation cylinder. That is, the translation cylinder is used to drive the tube pressing plate 531 to move in the front-to-back direction. The tube holding lifting device 540 is a lifting cylinder. That is, the lifting cylinder is used to drive the tube holding plate 541 to move in the up-down direction. Here, the tube pressing plate 531 and the tube holding plate 541 are driven by pneumatic means, and can also be driven by electric or hydraulic means, such as electric drive or hydraulic drive.

[0035] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments.
